A millimeter-wave dual-band filter based on high-order mode resonant cavity
Abstract
Abstract In this paper, a millimeter-wave dual-band filter with a W-band operating frequency is proposed based on a multi-mode resonator. Based on the research of multimode resonators, an ultra-wideband filter and a filter with transmission zeros are designed. By cascading and optimizing, a dual-band pass filter working in the W-band is designed. The two operating bands are 84.96 GHz ∼ 89.33 GHz and 96.57 GHz ∼ 103.64 GHz, respectively, and the 3 dB fractional bandwidth is 5% and 7.1%, respectively. The designed structure is prepared by using the CNC process. After testing, the test results agree with the simulation results. The 3 dB fractional bandwidth errors of the two operating bands are 0.5% and 1%, respectively.
